The only thing that comes to mind is disabling Aero which you've probably done already

Nice .. should be a great compound for someone to study how cross and dot product can be used.

Ps I see a "screenshot of the week" coming

A suggestion: Computing radiosity using ICE

Magog: Not sure. I would think the cuda controller takes care of it, and present the 3 cards as 1 device to iRay Mr Core: Thanks for contributing! Lighting and mats looks good but I gotta say I'm not really convinced by how iRay does dof. It just looks washed out, mental ray's normal dof looks bette...

i was afraid displacement happens outside the card. ICE Instancing seems to do too ((

It's the same one just packaged

If you see 'no cuda devices found' in the error log, that means your graphics card isn't supported. I've had some trouble running cuda on a mobile card even though it officially supported cuda.

Not sure, you'd have to try by installing the plugin &setting the options mentioned above&opening a render region.

It works with any modern graphics card and newer softimage releases. Nothing else is required.

Testing max polycount with a zbrush model... around 1.2 million quads seems what at most goes into the 768MB of my gfx card .. so a 3GB card would hold around 5 million polygons

another test using additional_color and dof
(10 minutes rendertime/gtx460/768mb)

Hi! To get some interest going for the combo IRay+SI, I figured it might be a good idea to start this thread along with some info on how to get started and a place to collect community test renders&tips. ...so without further ado... To get started... Installl ctrl_ghost_settings from here (IRay ...

Kzin, thanks for the tip. I tried Unified with Rasterizer+IBL but got stripe artefacts with low IBL quality settings. But got a 5-10% speedup for the Light rig+shadowmap render, without quality loss. Have yet to try Scanline+IBL+Unified but am guessing that it'll be too slow. Light rigs+shadowmaps f...

Hey this looks really cool - I haven't been able to get anything like this. Is it possible to post the file so I can deconstruct it and find out what I'm doing wrong? I wouldn't need the geo, just the hair cloud, lighting, and render settings... I took a look at your other file (with the cube) and ...

Here's a hair test btw, rendered with MR's IBL accelleration.
Ca . 10 hr but no render settings tweaking, max IBL quality.
Would need stronger specular settings and some thickness+length gradient for a more realistic hairline

Tried updating, my redraw issue wasn't fixed by updating the driver (GTX 285), but it's not so bad.. only happends once every few hours. If it's really annoying for you, still could be worth the try. Can't hurt.. usually .
